Step 1 : Introduction to the question "The Tet Offensive occurred during which war?"
...The Tet Offensive was one of the largest military campaigns of the Vietnam War, launched on this day in 1968, by forces of the Viet Cong and North Vietnamese Army. Though U.S. and South Vietnamese forces managed to hold off the attacks, news coverage of the massive offensive shocked the American public and eroded support for the war effort. The series of surprise attacks, named for their occurrence during the lunar New Year (or “Tet”) holiday, was a major turning point in the Vietnam War and the beginning of the slow, painful American withdrawal from the region.
